Problem Installing a Package

I have just installed the latest version of R on a openSUSE 12.1 system 
running on an ORacle VM VirtualBox and have encountered a problem with 
installing ChemometricsWithR.  Here is the output:

library("compiler")
install.packages("ChemometricsWithR")

Installing package(s) into ?/home/computation/R/x86_64-unknown-linux-gnu-
library/2.15?
(as ?lib? is unspecified)
also installing the dependency ?TIMP?

The openSUSE package installer didn't find a package Tcl/TK

Assistance and advice will be much appreciated.

Thanks in advance.
